Ottawa researchers develop âbarrel-eliminatingâ optical element

The âspaceplateâ is a new approach to manipulating light that could lead to paper-thin cameras, telescopes, and smart phones.
Flatter phones? optics are miniaturized with new counterpart to lens. The concept of âspaceplateâ is a new approach to manipulating light that researchers from the University of Ottawa say could lead to paper-thin cameras, telescopes, significantly lighter high-performance cameras, and âcamera bump-freeâ smart phones.
The spaceplate is described as a new optical element, which the scientists say could turn these ideas into reality by dramatically miniaturizing devices, potentially impacting many of the applications in our lives.

Can you imagine one day using a telescope as thin as a sheet of paper, or a much smaller and lighter high-performance camera? Or no longer having that camera bump behind your smartphone? In a paper published in Nature Communications, researchers from the University of Ottawa have proposed a new optical element that could turn these ideas into reality by dramatically miniaturizing optical devices, potentially impacting many of the applications in our lives.
Sending photons encoded with quantum information through free-space for applications like quantum communication and imaging are currently limited to channels with direct line-of-sight and low-noise. Researchers at University of Waterloo, Canada, have demonstrated a technique to encode quantum information in photons that will survive scattering from diffuse objects, while recording an image. This research could open up new possibilities for non-line-of-sight quantum channels and broaden the application of quantum communications or imaging to scattered signals.
